Field of application

The weight-optimized Promag L is suitable for applications in the water and wastewater industry. Due to its lap-joint flange concept, the flowmeter offers flexible and easy installation. Promag L 400 saves time and costs thanks to the broad functionality of its water- and wastewater-optimized transmitter. In addition, Heartbeat Technology ensures compliance and process safety at all times.

  • The bidirectional measuring principle is virtually independent of pressure, density, temperature and viscosity

  • Suitable for applications in the water and wastewater industry.

Device properties

  • Up to 30% less sensor weight

  • Nominal diameter: DN 25 to 2400 (1 to 90")

  • Maximum reduced installation length to DVGW/ISO

  • Transmitter housing made of durable polycarbonate or aluminium

  • WLAN access

  • Integrated data logger: measured values monitoring

Benefits

  • Reduced installation costs – flexible mounting by lap-joint flange concept (DN < 350/14")

  • Energy-saving flow measurement – no pressure loss due to cross-section constriction

  • Maintenance-free – no moving parts

  • Safe operation – no need to open the device due to display with touch control, background lighting

  • Time-saving local operation without additional software and hardware – integrated web server

  • Integrated verification – Heartbeat Technology
